Lossing phone signal

Hi
everyone does anybody have this problem the Xda Exec sometimes loss the network signal and then it does not connect to the network until you do a soft rest or go in to flight mode and back out and then it pick up the network.
I've try diffrent settings like connecting to the network manually does not work automatically some thing, any help.
The radio version that I have is 1.04.02
The Rom version is 1.13.48 WWE
The protocol version is 42.37.P8
The ExtRom Version is 1.13.139WWE
Thank you Gigino

Yes I've had the same problem occur to me several times, although I'm not sure it's actually losing the signal before that or not, but I'll look at my phone or take it out of standby and the phone will be off for no reason. I have to put it into flight mode, then take it out for it to work again.
I have a an Arabic enabled KJAM.
Rom version 1.1.9.3
Radio version 01.01.10
Protocol version 4.0.13.16
ExtRom Version 1.1.9.105

I have worked out that if you go into phone setting and network selection, select GSM only it should currently show GSM/UMTS and then in preferred neworks select your own network and move it to the top of the list, this solves the problem.

Thanks treblechance, that seems to be the source of the problem. Although there wasn't any option for GSM/UMTS (the KJAM doesn't support UMTS only the JASJAR). However I went into "Phone > Menu > Options > Network >Set Networks" and found my network at the bottom of the list and it wasn't checked. So I moved it to the top of the list and checked the box (I left network selection on Automatic) and it seems to have fixed it for now.

not a problem, noticed it with every single one i sold

This seemed like it might the same problem I've been having. It's the same symptoms, though I had blamed it on either a flakey radio hardware module, or a flakey radio driver.
Does anyone have any more information about this? It doesn't seem like just changing the network order should really be regarded as a good solution (though at this point, I'd happily take it as a workaround!), since isn't that just making the problem less likely to occur (suppose you traveled a lot, so were always roaming)?
Also, in my case I'm a T-Mobile subscriber, and there's 16 or so T-Mobile entries in the network list, with no identifiers to tell which part of the network they are for. I suppose if I could find my network number I could manually add it to the top, but not sure how to find it, or whether this really helps with the hung up radio connection enough to bother with.
Anyone have any more updates on this topic since 12/18?
Thanks!

1.20 Radio Rom takes long time to reregister on network after dropped off?

Hi all,
I'm currently experiencing a problem where my Softbank X01ht drops off the cellular network because I live in a low strength area, and takes forever, if at all, to automatically connect back to the network, even if I move into an area where I know the cellular strength is high.
If I manually turn off the phone portion of the hermes, and reconnect, then it happily detects the cellular network and connects. In other words, after disconnecting, it acts as though there is no network in range at all, even though I know there is.
This seems to have started after I upgraded my radio rom to version 1.20 from 1.07. Prior to the upgrade, I know it connected back to the network quite quickly after it dropped out. Has anyone else experienced this with the 1.20 Radio Rom? I currently have the Imate jasjam rom installed on my phone with the 1.04 bootloader.
Unsure if this is related, but the area that I live in has a weak UMTS network, but a relatively decent GPRS network. I'm thinking the phone is getting confused over which network to connect too.
It also seems that if I'm in an area with a pretty strong cellular strength, it doesn't drop out? Would I benefit from downgrading to the 1.16 Radio Rom?
Thanks in advance all.

I can also confirm that things added with that after a soft reset sometime it cant detect network..i have to manualy turn off/on the radio part....generelly it occures if i reset the set just after making a call or just getting disconnected from edge...
the previous 2 radio that i used 1.16 and 1.08 didnt suffer from those probs...
but the main benifit of 1.20 radio that i get is EDGE speed i can pump upto 220Kb (22-24 KB) download speed in flat when connected to pc as wireless modem but with the previous radios i can barely go 160Kb and the speed did uped/down regularly...
and somewhat strange with this 1.20 radio i cant search for network list manually when even i go to manual in network after sometime i get cant read error...but previous radios where ok in that par too...
and the last benifeat that i get with 1.20 is now the SIM STK menu is working.....

Thanks sajib,
Glad I'm not the only one experiencing it. For me, however, it only occurs when it looses connection to the cellular network. After every soft reset so far, it has connected to the cellular network automatically. To me it doesn't seem to even search for the network. That is, after loosing connection, it is resigned to the fact that it can't connect to a network, so doesn't even try, unless I force it too. I think I have seen it connect automatically once or twice, but either way, it takes at least 10-20 minutes, sometimes it never connects, and I force a manual reconnect by turning off the phone and turning it back on. So is this a known problem with the 1.20 Radio Rom?

Try this...
I had the same problem on my TyTn. Took forever to WiFi connect. Then I found this registry setting:
[HKLM\Comm\TIACXWLN1\Params]
"dot11ShortPreambleInvoked"=dword:00000001
Now my WiFi time-to-connect seems much faster.

Hi!
Thanks for the advice, but mine isn't a Wifi problem, but a problem with connecting to the cellular network.
Or do you think that your connecting to the WiFi network and the cellular network are one in the same?

i am using the 1.20 radio as well, but cant say that i have had any of the said problems... i have the cingular 8525 and have used the 2 latest cingular roms, the aku2.3 and 2.6.. but i did have some of the same problems with i used cingulars 1.16 radio

Do you commonly get cellular network disconnects? I find that if I'm moving around the city or driving around in the car, the network connection is maintained, and sometimes will automatically find the network if it does get disconnected. However, it is only when I am home that the phone disconnects and doesn't try to reconnect once it has been disconnected.
Any idea of what might have caused this issue with you with the 1.16 Radio Rom? Possibly something to do with the AKU version? I'm using AKU 2.3.
Thanks,
Gene

I too have the original problem but have not upgraded the radio ROM. I have the T-Mobile Vario II (sorry not sure what ROM that is) but often when I move from an area of either very weak or no signal to an area with a signal (coming out of a shielded building) I too get the same problem. Initially the phone shows weak (or even strong) signal strength but when I try to make a call I get the box up on the phone screen telling me it cannot connect. I have found that eventually it will, when left to it's own devices, get itself sorted out and allow a connection. But it is invariably quicker turing off the phone (via comm manager) then back on - this always results in a valid connection.
Perhaps the problem that you describe is not related just to the 1.20 Radio ROM upgrade?

Hi Tony,
It could possibly be an application or the ROM itself causing the problem, however, I think its the radio rom in my case, simply because this problem only started occuring after I upgraded to the 1.20 Radio Rom. Previously on the 1.07 Radio rom, the phone would connect automatically and immediately. Also I just performed a hard reset after I discovered this problem, and it still seems to be occurring...
I also am sure that after a long while the phone reconnects, I have seen it try reconnect a couple of times. But then again, a couple of times I've left it for 10-30 minutes, and it hasn't reconnected. Unsure of exactly how it chooses to reconnect and when it tries to reconnect. You would think it would try reconnect constantly after a specified period, but in my case it seems very random.

i actually get pretty solid coverage whether moving or stationary. especially at home since i live not a quarter mile from a cingular tower and i dont think its necessarily related to the aku version since i have gotten the same result with either 2.3 or 2.6. But i can say for sure that the cingular 1.16 radio is junk my biggest complaint was gsm calls cutting out and on my calls on 3G had a very weird digitized background noise, kinda sounded like a bad digital echo... 1.20 fixed all of that for me

When I'm roaming around my connection always seems to be sustained. e.g, I've been checking my phone ever 1hour for about 24 hours, and have yet to see my signal lost. Is it possible that the phone is getting confused over which band to connect to? As I said in my first post, I have a relatively weak 3G/UMTS signal from my home (1-2 bars), and a relatively strong GPRS signal (3-4 bars). Presumably the phone is UMTS-preferred, and uses GPRS as a secondary.
I saying this, even if I go to another area which usually has 5 bars UMTS signal, I haven't seen the phone immediately connect. This was after about 10-15minutes waiting in that area.

yes, the phone is set to prefer the UMTS bands.. have you tried setting the band manually instead of it letting it autosearch? you can do it in the phone settings menu or use the app listed here: http://forum.xda-developers.com/showthread.php?t=286844

No GSM Error Tried Wiki already

Guys here is my situation. I have a Cingular 8525 for some time now I noticed that it was dropping signal and then recovering it I thought it was a radio problem but I changed numerous radios and it didn't fix the issue. Last night I noticed that it wasn't picking up any signal, on turning it on I noticed that I had No GSM I tried the way in the Wiki but I am unable to flash using the radio 1.16 to it I unchecked Allow USB connections but for some reason I cannot flash the radio. I started the phone attempted to flash the phone with several other radios and it just hangs. On rebooting I see NO GSM but when my phone starts up I see it reads the network but I cannot do anything else no calls nothing. Is there another way to flash the radio to my device or is the radio just dead? If so I have another 8525 thats not working can the radio part of it be changed?
Regards

It seems your phone is toggling between 3G and the older GPRS. By default, the 8525 automatically selects 3G if it is available. If you move out of 3G range (considering 3G support nationwide isn't great yet), which will happen often, you will lose signal temporarily and either switch to GPRS or regain a 3G signal. Currently I default my phone to use GPRS just because i can't be bothered with having to deal with dropping signal/calls as often as i used to with the automatic setting. There is a free tool called BandSwitch which can accomplish this for you. The newer version (2.1) is not free but if you can get your hand on the older version which is, it'll work satisfactorily well. I hope this solves your problem.

I had the same problem and nothing worked for me.
Try different solutions posted my various users and see if anytihng works for you.
I think it is a hardware radio problem and probably the only solution is to change the motherboard.
If it is still under warranty - get it done. If not, you are out of luck.

TD2 losing network reception - handset or network at fault?

Hi guys, I'm hoping one of you knowledgeable people might be able to help please, I've done a bit of seraching/googling but not really got anywhere...
I've noticed over the last few days that my TD2 keeps losing reception in places where I normally have a very good signal - e.g. the handset will be sat on my desk at work for a while, and when I pick it up to use it to make a call, send a text etc I notice that the network icon on the taskbar at the top is showing an exclamation mark to indicate there is no signal. I have to power off the handset and turn it back on to clear this problem (I've tried going to the comm manager and disabling/enabling 'phone' but when I disable it I cannot re-enable it afterwards).
I was wondering if this is a problem with my handset or the network (T-Mobile UK)?
Anyone got any ideas please?
Device information in case it's needed:
ROM Version: 1.39.405.2 (47382) WWE
ROM Date: 04/07/09
Radio Version: 3.43.25.19
Protocol Version: 61.20t.25.10U

I had the same problem in areas where the 3G signal is weak. I disabled 3G and everything is OK. I also noticed a dramatic increase in battery life.

I get this every 2-3 weeks (known strong signal area, no reception at all indicated), it could a bug in the Radio ROM, perhaps? Updating the Radio ROM might help. But this...

..doesn't sound right. I do this and it clears the problem without restarting the phone.

@ kskar - Sometimes I'm in a good 3G area when this happens (Manchester city centre, UK) and sometimes I'm not (at home), so I don't think this would be causing it.
@ Pete_S - I was wondering if it could be anything to do with the Radio ROM... I also tried turning airplane mode on/off in comm manager, but it usually won't come out of airplane mode either without powering off & back on.

You could also try constraining the phone to operate only in the UK bands (phone settings - Band - GSM(900+1800) + UMTS(900+2100)) and, if you only use 3G, set network type to "WCDMA".

GSM connection problem

I am only writing here after I tried everything I could possibly imagine with no result. Sorry the long text.
I'd like to hear ideas from you. Anyone with a similar problem.
I have a Blackstone, and never had even the smallest problem with GSM signal. But now I face the following:
- If I set the Band to "Auto", my phone connects to the HSPDA network with no problem, and I use internet and make calls normally.
- If I set the band to "GSM", sometimes it connect, sometimes not. When I manage to connect, if I try to use the internet, sometimes I lose the signal. When I am making a call, it frequently hangs up. The problem is random, sometimes I can use GSM with internet and calls for a long time, but suddenly it crashes again!
The solution would be always connect to HSPDA, but the problem is that on "Auto" the phone sometimes goes to GSM alone, and the signal breaks down.
I cannot be sure exactly when this problem began. But it was after I installed PDAVIET's Rom (WM 6.5 21053 and manila 2.5), and radio 1.17.25.09.
Among everything I have done:
- Flashed dozens of Roms always hard-reseting twice after. Tried stock Roms, cooked Roms with WM 6.1 / 6.5, manila 1.3 / 2.1 / 2.5.
- Flashed radios 1.13 / 1.14 and 1.17 in combination with all Roms. Tried with and without ripphone.dll's
- To eliminate a operator problem, I used my chip on a nokia for a few days, and didn'd have a single problem with signal, calls, internet. I installed a chip from another operator and faced the same problem.
Nothing I have done made any result.
Even using my stock Rom didn't solved. I used this phone for 8 months with no problem. So I came to the conclusion this is hardware related, with the antenna or something.
Thanks

All right, have been through a few more Roms and Radios and the problem remains unchanged...
Really looks like an antenna related problem. Apparently I will never connect to GSM again unless I take my device to service (have no guarantee), and be lucky!
But anyway, I found a solution to the connection instability and phone calls interruptions. Solved my life for now. It is very complicated:
*********************
HKLM\Software\OEM\UMTS
OpMode=2
*********************
This forces the phone to always stay in the 3G band. The "Auto" mode you can set in Comm Manager lets the phone change to GSM when the signal is low or whenever he wants, and my connection breaks down.
BTW, other modes are:
OpMode=0 (Auto mode)
OpMode=1 (GSM only mode)
OpMode=2 (3G only mode)
I know this may not be useful for anyone, but I just felt like sharing...
